Abstract
The utility model discloses an 8-byte grid steel frame cold pressing device. The device comprises a machine body and a hydraulic system, wherein the machine body is provided with a cold pressing workbench and a hydraulic jack; the hydraulic system is used for controlling the operation of the hydraulic jack; the cold pressing workbench is provided with a V-shaped cavity; the hydraulic jack is positioned right above the V-shaped cavity; and a crown bar of the hydraulic jack is provided with a V-shaped pressure head adapting to the V-shaped cavity. During the operation of the 8-byte grid steel frame cold pressing device, the grid steel frame is placed on the cold pressing workbench, the hydraulic system controls the hydraulic jack to push the V-shaped pressure head to press toward the 8-byte grid steel frame, and cold press molding is carried out on the grid steel frame. As a result of the common limit function of the V-shaped pressure head and the V-shaped cavity, the molding accuracy of the grid steel frame is high; and besides, since hydraulic automatic operation is adopted, the production efficiency is high, and the labor intensity is low.
Description
Technical field
The utility model relates to a kind of grid steelframe cold press device, particularly a kind of cold press device of the 8 byte grid steelframes that are used to cold pressing.
Background technology
Along with Railway Market strengthens safety, quality requirement gradually, the construction of railways supporting measure progressively turns to " 8 " byte grid steelframe by original general grid steelframe." 8 " byte grid steelframe is becoming " 8 " word muscle by original " U " type muscle in the capable shelf structure in the common grid steelframe.The master of " 8 " word muscle of " 8 " byte grid steelframe looks and is shaped as ⅴ shape, plan view shape is the figure of eight, need be existing in manufacturing process with the cold completion figure of eight of grid steelframe blank, again it is cold-pressed into ⅴ shape.
Because the special shape of " 8 " byte grid steelframe; The clod wash equipment that is used for the common grid steelframe of clod wash " U " type muscle can not be accomplished the operation of colding pressing of " 8 " byte grid steelframe, therefore needs a kind of cold press device that " 8 " byte grid steelframe is cold-pressed into ⅴ shape.
The utility model content
In view of this, the purpose of the utility model provides a kind of 8 byte grid steelframe cold press devices, and it can be cold-pressed into ⅴ shape with " 8 " byte grid steelframe, and has and improve that formed precision is high, production efficiency is high and reduce advantage such as labor strength.
The utility model 8 byte grid steelframe cold press devices comprise body, and body is provided with cold pressing workbench and hydraulic jack, also comprises the hydraulic system that is used to control hydraulic jack work; The workbench of colding pressing is provided with the ⅴ die cavity, hydraulic jack be positioned at the ⅴ die cavity directly over and the push rod of hydraulic jack be provided with the ⅴ type pressure head adaptive with the ⅴ die cavity.
Further, also be provided with the locating piece that is used to limit 8 byte grid steelframe end positions on the said workbench of colding pressing.
The beneficial effect of the utility model: the utility model 8 byte grid steelframe cold press devices, the grid steelframe is positioned on the workbench of colding pressing, the HYDRAULIC CONTROL SYSTEM hydraulic jack promotes ⅴ type pressure head and presses to 8 byte grid steelframes; The grid steelframe is cold-pressed into type; Because the common position-limiting action of ⅴ type pressure head and ⅴ die cavity, grid steelframe moulding accuracy is high, and adopts the hydraulic pressure automatic job; Production efficiency is high, and labour intensity is low.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 looks sketch map for the master of the utility model 8 byte grid steelframe cold press devices;
Fig. 2 is along the cutaway view of A-A among Fig. 1.
The specific embodiment
Fig. 1 looks sketch map for the master of the utility model 8 byte grid steelframe cold press devices; Fig. 2 is along the cutaway view of A-A among Fig. 1.
As shown in the figure, present embodiment 8 byte grid steelframe cold press devices comprise body 1, and body 1 is provided with cold pressing workbench 2 and hydraulic jack 3, also comprises the hydraulic system 4 that is used to control hydraulic jack work; The workbench 2 of colding pressing is provided with ⅴ die cavity 5, hydraulic jack 3 be positioned at ⅴ die cavity 4 directly over and the push rod of hydraulic jack 3 be provided with the ⅴ type pressure head 6 adaptive with ⅴ die cavity 5.
During this 8 byte grid steelframe cold press devices work, the grid steelframe is positioned on the workbench 2 of colding pressing, hydraulic system 4 control hydraulic jack 3 promote ⅴ type pressure head 6 and press to 8 byte grid steelframes; The grid steelframe is cold-pressed into type; Because the common position-limiting action of ⅴ type pressure head 6 and ⅴ die cavity 5, grid steelframe moulding accuracy is high, and adopts the hydraulic pressure automatic job; Production efficiency is high, and labour intensity is low.
As improvement to this embodiment, also be provided with the locating piece 7 that is used to limit 8 byte grid steelframe end positions on the said workbench 2 of colding pressing, locating piece 7 is set can improves piece installing efficient and piece installing precision, can make the formed precision of 8 byte grid steelframes higher.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
